When selecting a computer for use as a PDC or BDC, use the hardware guidelines in Table 2.7, below. The table assumes that the computers will function only as PDCs and that no other major Windows NT operations will occur, such as moderate file server, SQL server, SNA server, and remote access server. All numbers are in megabytes (MB) and it is assumed that the computer's pagefile size is at least 250 MB.
